Inflammatory bowel disease (IBD) is a group of intestinal chronic non-specific inflammatory disease with unknown etiology, and includes ulcerative colitis (UC) and Crohn''s disease (CD).Studies have indicated that environmental factor, genetic factor, disorder of immunity are associated with the pathogenesis of IBD.More and more basic and clinical studies focus on treatment with helminths in IBD.The accumulated evidences have shown that helminths infection has beneficial effects on the alleviation of IBD and is relatively safe.This article reviewed the advances in study on helminths in the treatment of IBD.

0.05) while other indicators did not. All the data were simply related to each other. The primary influencing factors to NDS score 1, in decreasing order of impact were volume of infarction, position of infarction, hs-CRP and FBS. While the primary influencing factors to NDS score 3 at the end of 1 month treatment, in decreasing order of impact, were NDS score 1, size of infarction, FG, hs-CRP and TC. Conclusions Volume of infarction and hs-CRP are very important determining factors in both NDS score 1 at the beginning of the treatment and NDS score 3 at the end of 1 month treatment. However, in determining NDS score 3 at the end of 1 month treatment, the impact of FG is greater than hs-CRP. The other influencing factors include FBS, TC and so on. Therefore we conclude that it is helpful to recover from neurologic deficit through lowing these influencing factors directly by medication.

Objective To explore the effects of inhaled nitric oxide(NO) on expression of plasminogen activator inhibitor-1 (PAI-1) mRNA and protein in the early-stage of experimental acute lung injury (ALI) in a rat model.And to investigate the relationship between endogenous NO system including inducible nitric oxide synthase (iNOS)and intrapulmonary NO production and expressions of PAI-1 in ALI.Methods In the study,endotoxemia followed by the second attack due to intratracheal injection of lipopolysaccharide (LPS) in rats caused ALI.Male SD rats aged 4-5 weeks (clean conventional rats,180-200 g) were randomly assigned to 2 groups:saline control (C) group,LPS-treated (LPS) group,and the 2 groups were randomly allocated to subgroups exposed to air (A) or 20 × 10-6 NO.They were sacrificed for 24 h.Expressions of PAI-1 mRNA of the lung tissue were evaluated by real-time polymerise chain reaction; PAI-1 proteins were determined by immunohistochemistry.NO production in the lung tissues and pulmonary iNOS activity were measured.Meanwhile,histopathological lung injury scores were evaluated and modified martius acid fuchsin brilliant blue(MSB) stains was performed to evaluate fibrin of the lung tissues.Results At 24 h time point with intervention of iNO,PAI-1 mRNA and protein levels in LPS-NO subgroup were decreased compared with those in LPS-A subgroup (4.94 ± 0.52 vs 5.56 ± 0.27 ; 1.31 ± 0.40 vs 1.69 ± 0.16,all P ＜ 0.05).Meanwhile,iNOS activity and NO productions in LPS-NO subgroup were lower than those of LPS-A subgroup [(0.84 ± 0.36) U/mg prot vs (2.30 ± 0.25) U/mg prot ; (1.90 ± 0.84) μmol/g prot vs (3.38 ± 0.73) μmol/g prot,all P ＜ 0.05].iNOS activity had significant correlation with expression of PAI-1 mRNA and protein in lung tissue (r =0.481,P =0.005 ; r =0.667,P =0.000) ; NO production had significant correlation with expression of PAI-1 mRNA and protein in lung tissue(r =0.532,P =0.002; r =0.784,P =0.000).At 24 h time point,the histopathologic lung injury scores in LPS-NO subgroup were decreased in contrast to LPS-A subgroup (4.28 ±0.94 vs 6.12 ± 1.51,P ＜ 0.05).Fibrin deposition evaluated by modified MSB stains in LPS subgroups was found in alveolar space,lumen of blood vessel and mesenchymal ;LPS subgroup with NO appeared a decreasing trend in contrast to LPS subgroup with air.Conclusions Inhaled nitric oxide of 20 × 10 6 can suppress elevated expression of PAI-1 in ALI induced by endotoxin.This inhaled NO can improve the imba-lance of plasminogen activation system and alleviate lung injury.Meanwhile,inhaled NO down-regulates intrapulmonary iNOS activity as well as endogenous NO productions in rats with 2 hits of LPS induced ALI.These changes also have a close correlation with down-regulation of PAI-1 mRNA and protein.Thus,regulation of endogenous NO system on the expression of PAI-1 will be the future direction of new therapies for ALI.

Objective This article was designed to observe the effects of astragalus polysaccharides (APS) on glucose and lipid metabolism, and on expressions of proxisome proliferator activated receptors-α (PPAR-α) and its downstream genes in diabetic hamsters cardiomyopathy. Methods Forty-five hamsters were divided into 3 groups randomly: normal control group (15 normal hamsters), diabetic control group [15 streptozotocin (STZ)-induced diabetic hamsters], and astragalus polysaccharides (APS)-therapy group (15 STZ-induced diabetic hamsters administered with APS 2 g/kg per day orally for 10 weeks). The levels of insulin, C-peptide, myocardial enzymes, glycosylated serum protein (GSP) and lipoprotein of all hamsters were measured. The ultrastructure of myocardium was studied, and the gene and protein expressions of PPAR-α, FATP and ACS were also detected by fluorescent quantitative RT-PCR and Western blot. Results It was shown that Compared with DM group, the levels of GSP, myocardial enzymes and lipoprotein of hamsters in APS-therapy group were lower, the myocardial ultrastructure of hamsters in APS-therapy group was well-protected, and the gene and protein expression of PPAR-α, FATP and ACS of hamsters in APS-therapy group were higher. Conclusions APS is partly effective in treating diabetic cardiomyopathy.

OBJECTIVEThis work lays the foundation for establishing a digital model database with normal occlusion. A digital dental cast is acquired through grating projection, and model features are measured through reverse engineering.

METHODSThe grating projection system controlled by a computer was projected onto the surface of a normal dental model. Three-dimensional contour data were obtained through multi-angle shooting. A three-dimensional model was constructed, and the model features were analyzed by using reverse engineering. The digital model was compared with the plaster model to determine the accuracy of the measurement system.

RESULTSThe structure of three-dimensional reconstruction model was clear. The digital models of two measurements exhibited no significant difference (P > 0.05). When digital and plaster models were measured, we found that the crown length and arch width were not statistically different (P > 0.05), whereas the difference between the crown width and arch length was statistically significant (P < 0.05).

CONCLUSIONThe reconstruction of a digital model by using the grating projection technique and reverse engineering can be used for dental model measurement in clinic al and scientific research and can provide a scientific method for establishing a digital model database with normal occlusion.
